Karl,
It's just a new delivery system(thickened unmixed West in a caulk tube). I used West system and fiberglass fibers to seat my beams. Just make sure you use a good mold release on your beams to pop them back out or you'll have the problems Mike is referring to.
Mike,
Seating the beams is just taking up the factory's slack. You use a mold release or wax (or both) on the beams and fill in the voids.
I ended up taking Eric Arbo's advice and getting a 13' X 26' party tent for a temporary shop.$369 off E-bay w/ free shipping. Just got it today but won't be able to do anything until after the little race next week.
